Very practical.

Great multipurpose product. Use it as a raincover for small backpacks or use it independently for day outings. Stow it away when not in use.

Defective product. Check carefully before buying

Since it is rolled into a small cover, I didn't notice at the time of purchase. But it had some holes in it, which I discovered only later after reaching the country. So check completely for any defects before buying.

Additional Product Information


Main fabric

  • 100% Polyester cationic

Backpack technical tests

We conduct laboratory tests to approve the components: fabrics, buckles, straps, foams, zippers, etc. For example, for a fabric: resistance to wear, tearing, colorfastness in UV rays, washing, waterproofing, etc. A final test on the finished product simulates the kind of treatment to which it will be subjected over several years, to assess the strength of the assembly. The pack is filled with weights and placed on a dummy that replicates thousands of cycles of a fast walking motion.

How is backpack volume measured?

The volume of each backpack is measured using a standardized method: we fill the main compartment as well as each pocket with little balls. Then we empty the balls into a graduated container to find out the equivalent number of liters.

A score for comparing the products' environmental impact

The product's environmental impact is calculated over its entire lifecycle using various indicators. An overall rating from A to E is provided to help you easily identify the more eco-friendly products by comparing products of the same type (T-shirts, pants and backpacks, etc.) Decathlon is committed to displaying the environmental information of its products.
